Electron Positron Micro Collider

In any process that produces electron-positron pairs such as the well known trident process in the Coulomb field of high Z nuclei, the electron and positron will be born at essentially the same location and will oscillate in anti-phase in the laser field. With the superimposed oscillation and drift at large values of a0 = eE/m the particles will not return to their birthplace but will accurately re-collide since the drift is proportional to e2. Essentially all pairs will collide giving a huge increase in luminosity compared with a convention electron-positron collider. At 1026 Wcm-2 the collision energy will be around 5GeV and the pairs will be spin-correlated.
